Patented Dec. 9,1913.

To all wko/m, t may concern.'

Be it .known that I, HENRY W. STARK- WEATHER, a citizen of the UnitedStates, residing at New Haven, in thevcounty of New Haven and State ofConnecticut, have invented a new and useful Improvement inMuslirooniBullets; and I do hereby declare the following, when taken inIconnection with the accompanying drawings 'and the characters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of thisapplication,and represent, in Figure l, a View in side elevation of amushroom bullet constructed in accordance with my invention, with aband-like jacket swaged thereupon. Fig. 2, a view thereof in centrallongitudinal section.

My invention relates to animprovement in jacketed mushroom bulletscharacterized by a band-like jacket exposing the soft metal of the bodyor core `beyond its opposite edges, the object being to produce at a lowcost for manufacture, a bullet of superior mushrooming effect.

IVith these ends in view my invention consists in a mushroom 4bullethaving certain details of construction as will be hereinafter describedand pointed out in the claim.

In carrying out my invention as herein shown, I apply a relatively hardsheetmetal band-like jacket, 2, to a soft metal body, 3, upon which theband is swaged so as to be embedded in the surface thereof, the innerend of the band being bent inward to form an annular anchoring flange orcrimp, 4, which is embedded in v*the body,

3, and holds the band firmly thereupon. The nose, 5, of the soft-metalbody is eX- posed beyond the outer edge of the bandlike jacket, 2, andis therefore free to mushroom upon impact.

To prevent any portion of the band, 2, from engaging with the rifling ofthe arm in which the bullet is used, the band is made in its largestpart a trifle smaller in diameter than the exposed rear end, 6, of thebody which is cylindrical in form and provided with a shallow annulargroove, 7, for the reception of a lubricant.

I claim:

As a new article of manufacture, a mushroom bullet having a soft-metalbody made cylindrical at its rear end to take into the rifling of agun-barrel and tapering forward from its cylindrical portion to form arounded nose, and a band-like jacket swaged upon the said soft-metalbody and narrower in width than the length thereof to expose thecylindrical rear end thereof and the rounded nose thereof, and the inneredge of the said band being turned inward to form a retaining-Harige orcrimp which is embedded in the metal of the body at a point in front ofthe cylindrical portion thereof and where the body begins to taperforward.

In testimony whereof, I have signed this specilication in the presenceof two subscribing witnesses.

HENRY W. STARKVEATHER.

THOMAS C. JOHNSON, FRANK A. PAUL.
